Can the Xbox One Output Audio Via Optical Cable?

This guide answers the common question regarding digital audio connections on Microsoft consoles. It confirms which Xbox One models feature an optical port, details the steps to configure audio settings for surround sound, and provides solutions for users with models that lack this specific output.

Model Compatibility

The ability to output audio via an optical cable, also known as S/PDIF, depends on the specific version of the console you own. The original Xbox One and the Xbox One S both include a dedicated S/PDIF optical audio out port on the rear of the chassis. This allows users to connect the console directly to compatible soundbars, AV receivers, or headsets that support optical input.

However, the Xbox One X does not include an optical audio port. Microsoft removed this feature from the Xbox One X to streamline the hardware design and reduce internal space usage. Users with the Xbox One X must rely on HDMI for all audio and video transmission.

Configuring Optical Audio Settings

For those with an original Xbox One or Xbox One S, connecting the cable is only the first step. You must configure the console to send the signal correctly. Navigate to the Settings menu, then select General, followed by Volume & audio output. Under the Speaker audio section, change the HDMI audio option to Stereo uncompressed if you are using a headset amplifier, or select Bitstream out for surround sound formats like Dolby Digital or DTS through a receiver.

Ensure that the optical audio format is also set to match your audio equipment. If your receiver supports 5.1 surround sound, select Dolby Digital 5.1. For stereo setups, choose Stereo uncompressed. Once selected, the console will route audio through the optical cable while video continues to transmit via HDMI.

Alternatives for Xbox One X Users

Since the Xbox One X lacks an optical port, users needing external audio processing must use HDMI ARC or eARC. Many modern TVs and soundbars support Audio Return Channel (ARC) through the HDMI connection. By connecting the Xbox One X to a TV via HDMI, and then connecting the TV to a sound system via another HDMI ARC port, you can achieve high-quality audio without an optical cable.

Another option is to use a HDMI audio extractor. This device splits the signal from the HDMI cable, sending video to the display and routing audio to an optical or 3.5mm output. This method allows Xbox One X owners to utilize older audio equipment that relies on optical inputs despite the console’s hardware limitations.
